@conference{10902/6454, year = {2014}, url = {http://hdl.handle.net/10902/6454}, abstract = {In this work, both arterial pulse and respiratory rate have been successfully measured based on changes in speckle patterns of multimode fibers. Using two fiber-based transducers, one located on the wrist and another in the chest, both disturbances were transmitted to the fiber, varying the speckle pattern. These variations of the speckle pattern were captured using a commercial webcam and further processed using different methods. The achieved results have been presented and the simultaneous monitoring of both vital signs has been also discussed. The feasibility to use the proposed sensor system for this application is demonstrated.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2014, 9157, 91572I}, publisher = {23rd International Conference on Optical Fibre Sensors, Santander, 2014}, title = {Speckle POF sensor for detecting vital signs of patients}, author = {Lomer Barboza, Mauro Matías and Rodríguez Cobo, Luis and Revilla Varona, Pablo and Herrero Diego, Gumersindo and Madruga Saavedra, Francisco Javier and López Higuera, José Miguel}, }
